Problems solved by technology

[0004] However, either overestimation or underestimation of the failure time can negatively affect the adjustment results
On the one hand, an overestimation of the failure time will lead to unoccupied platforms, i.e., the platforms are not occupied for a period of time after the repair is completed, thereby aggravating train delays; It is occupied by the arrangement before it is completely repaired, causing re-adjustment of the operation diagram, causing inconvenience to passengers, and even causing accidents

Embodiment

[0146] Such as image 3 A section of railway includes three stations and two sections, and each station includes two platforms. There are three trains going from station 1 to station 3, and one train going from station 2 to station 3.

[0147] Table 1, the original operation diagram

[0148]

[0149] The original running diagram is shown in Table 1. The safe time interval is equal to H=Δ=5min. If u is used to represent the operation time stipulated in the original operation diagram (referring to the station operation time or inter-station operation time), then the minimum stop time is equal to u-3, and the minimum interval operation time is equal to u-5, that is, at the station between stations d ij min = u - 5 .

[0150] Step 1. When the first platform of the first station fails due to equipment failure, the ground signal system reports the failure information ...

Abstract

The invention discloses a method and system for adjusting train working diagrams on the basis of platform redundancy. The method includes: when an original platform is invalid, an original working diagram is adjusted to generate a new working diagram, and the new working diagram distributes one new platform for each affected train; if the original platform is repaired successfully, the affected trains use the original platform continuously, and otherwise the affected trains use the new platforms. The method and system for adjusting train working diagrams on the basis of the platform redundancy gives full consideration to random nature of platform failure time. Compared with a traditional method, the method and system for adjusting train working diagrams on the basis of the platform redundancy can effectively reduce delay time and cost.

Description

technical field [0001] The invention relates to the adjustment of train diagrams. More specifically, the present invention relates to a method and system for adjusting train diagrams based on platform redundancy. Background technique [0002] The train diagram includes relevant information such as the time, sequence, and platform selection of trains entering and leaving the station. [0003] Affected by natural conditions, man-made accidents, and equipment failures, one or more stations may be unavailable for a certain period of time. In this case, the dispatcher needs to adjust the train diagram in time to avoid accidents, and at the same time minimize the negative impact of the adjustment of the train diagram. The existing train diagram adjustment systems all use certain quantities to estimate platform failure time. Although the research on train diagram optimization and adjustment systems for platform failure is very extensive, they do not consider the random nature of ...
